Solution Overview

Problem

Conventional portable radiography devices have insufficient display sizes, leading to reduced visibility and increased misreading rates of user control mode images, which hampers the effectiveness of intraoral radiography.

Innovation Solution

Incorporation of a projection unit that can project user control mode images and intraoral radiographs externally, utilizing technologies like LCD, LCOS, or DLP projections, allowing for improved visibility and legibility, and enabling the device to be more portable by replacing traditional fixed displays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a fixed-type display device is used in the portable radiography device, then the device structure is simple, but the display size is insufficient leading to reduced visibility and increased misreading rate

Engineering Contradiction:

ImprovevisibilityVSAvoiddevice structure

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The patent replaces the fixed mechanical display device with a projection system that uses optical principles to display images on external surfaces. The projection unit projects user control mode images and intraoral radiographs onto walls or other surfaces, eliminating the need for a large fixed display screen while significantly improving visibility and legibility of the displayed information.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Illumination intensity

If a large display is used to improve visibility of user control mode, then visibility is improved, but the device size increases reducing portability

Engineering Contradiction:

ImprovevisibilityVSAvoiddevice size

Core Design Contradiction:

Illumination intensityVSVolume of moving object

Solution Approach 1:

The patent substitutes the physical display screen with a projection system that displays images externally on walls or surfaces. This allows the device to maintain a compact, portable form factor while providing large, clear projections of user control mode images and intraoral radiographs, thereby improving visibility without increasing device volume.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a fixed display device is used, then the display function is stable, but the display location is fixed reducing flexibility

Engineering Contradiction:

Improvedisplay location flexibilityVSAvoiddisplay function stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent transforms the static display system into a dynamic projection system. The projection unit can project images onto various external surfaces such as walls, ceilings, or other surfaces in different locations. This provides flexibility in display location while maintaining stable projection function through the optical projection mechanism.

Inventive Principle:

Principle #15Dynamics
